In fact, the value stored in len has indeed been right-shifted by two bits. It needs to be left-shifted to be interpreted. Apologies if I wrote it in a way that was less than entirely clear, but I believe it was correct.

Yep, I misread what you wrote.

It depends on what the meaning of "is" is. :)

Something like "the len field contains the length with the two lowest bits lopped off" would
be clearer.
